STOJP-MOTION FOR LOOMS.

Application filed May 13,

To all who/:2 it may concern:

Be it known that I,-PI-IINEAs A. MILLIs, a citizen of the United States, residing at Lewiston, in the countyof Androscoggin and State of Maine, have invented certain new and useful Improvements in Stop-Motions for Looms; and .I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toa stop motion for looms, and the object is to provide'cerain means of novel construction for engagement with the feeler bar of a warp stop motion when the harness drops on account of the breaking of a harness strap, or from any other cause.

A further object is to provide for the operation of the :feeler bar of a Warp stop motion, by the use of a device engaged by the harness, when the latter stops, and comprising a transversely extending element mounted for vertical movement when en gaged by the harness and serving to actuate a pivotally mounted element, or elements, which impart a thrust to a connecting rod, and then to a device; directly contat-ting with the ieeler bar.

A still further object is to provide a plurality of pivotally mounted elements adapted to he rocked in opposite directions upon the downward movement of the transverse bar engaged by the harness, these rocking elements being so connected that they impart a thrust in the same direction to the connecting rod which actuates the pivoted element directly engaging the 'feeler bar.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed. I

In the accompanying drawing:

Figure 1 is a view of the device in elevation.

Fig. 2 is a View in vertical section, longitudinally of the upper element of the standard and of the bar movable vertically with reference thereto.

Fig. 3 shows the vertical elements of the standard, detached, these elements being adjustable. V

. bolted to the floor.

The upper element of the standard includes a vertical member 13 having a slot 14 therein, permitting this member to be bolted adjustably to the member 10, the bolt of course passing through one of the apertures 11.

The vertical element 13 of the standard carries at its upper end atransverse member 15, apertured as shown at 16, 17, 18' and 19. An upper horizontal bar 20 adapted for engagement by the harness, when the latter drops, has secured thereto guiding pins 21 and 22 passing through oppositely located apertures in the bar 15. Also connected with horizontalelement 20 are vertical pins or rods 24 and 25 which move with the bar 20. tical elements 13 of the standard extend laterally therefrom and on one of these brackets there is mounted a T-shaped lever pivoted at 28. This lever includes the arms 29, 30 and 31, the arm 30 being engaged by the pin 24 and operated upon the downward movement thereof and of the bar 20.

An angle lever 33 is pivoted at 34 and includes arms 35 and 36, the latter being engaged by the element 25 in the same manner that the element 24 engages the arm 30, on the opposite side of the device. An arm 38 constituting one element of the connecting rod between the angle lever and the T-lever, is connected with arm 35 at the point 40, the opposite end being connected with turn buckle 41, and the latter being connected with arm 39 which in turn is connected with the arm 31 of the T-lever at the point shown. It will be observed that the arms 29 and 35 move outwardly, and therefore in opposite directions when actuated by the pins 24 and 25 respectively. In this operation the lower arm of the T-lever is thrown inwardly or toward the standard,

Brackets 26 and 27 connected with vervice l6 having rigidly mounted thereon an i by means of a clamp 50.

for imparting a thrust to the device now to be described, for directly actuating the :teeler bar of the warp stop motion.

A bracket fixedly mounted has pivotally connected therewith 'a hook shaped 'dearm 17. This arm has pivotal connection with the rod e8 connected with the; rod 49 The rod 4.9 is pivotally connected with the arm 29, andthe latter imparts the required thrust to the connecting rods for throwing the hook up- .wardly into engagement with the feeler bar of the stop motion. A spring 52 is located and connected as shown, and serves an obvious purpose.

It is. apparent that various changes may be made in the form of the elements and in themanner of assembling the latter, within 20 the scope of the appended claims.

Having thus described the invention, what I. claim is-:--

$1. In a device of the class-described, a supporting element, a bar-mounted in a sub- -stantially horizontal position above said element andmovable vertically with reference thereto,.a pluralityot' pivotally mounted devices movable in opposite directions upon the downward movement of the bar, a device for actuating the ieeler bar of a warp -stop. motion,.aiid means for imparting thrust to said device last named in one direction,

upon the movement of said pivoted devices;

in opposite directions.

2. In a device of the class described, a supporting element, a bar mounted above said element in an approximately horizontal position and having vertical movement with reference to said element, a pivoted deviceincluding a plurality of arms extending at ail-angle to each other, and mounted on said standard, means for imparting movement to tions, means for operating said devices by the downward movement ofthe harness of a loom, 1a. feeler bar actuating device, and

means for imparting thrust thereto in one direction upon'the movement of said pivoted devices in opposite directions.

it. In a device of the class described, a horizontal bar mounted for vertical movement upon the dropping of the harness of a loom, a T-shaped lever actuated upon the the angle lever and the Tj-lever on opposite sides of the pivotal mounting of said levers, a device for actuating a feeler bar, and means connecting the dev ce last named with the T-lever. V V r 5. In a device ot'the class described, a

standard including an adjustable vertical element," a horizontal element supported thereby, a horizontal bar movable vertically with reference to the horizontal element first named, guiding devices for controlling such. movement, pins movable v rtically w1th the second named horizontalv element, pivoted devices mounted on the verticalelement ot' the standard andoperated;upon.v the vertical movementyoit' the pins, and means operated by themovement of the pivoted devices for actuating the feeler bar of a stop motion.

6. Ina device of the class described, a horizontally mounted bar adapted for vertical movement when engaged by he dropping ot a harness 01 a loom, pivoted devices and means .for moving the latter in opposite dir *ctions uponthe downward movement of the horizontal bar, a spring connecting the pivoted devices on corresponding sides of the pivotal points, means for connecting the pivoted devices on opposite sides of the piv-. 'otal points and comprising a plurality of arms-and adjustable means for connecting the arms, and means for actuating a feeler bar of a stopmotion upon theoperative movement oi the pivoted devices.

In testimony whereof I- affix my signature in presence of two witnesses. I
